Abstract In this study, four biochars prepared from different crop residue waste i.e. sugarcane bagasse (SBB), coconut shell (CNB), paddy straw (PDB), and distilled of lemongrass (LGB) were evaluated for removal Remazol Brilliant Blue R the aqueous system. The RBBR adsorption capacities biochar 97–79% SBB, 99.9–99.47% CNB, 66.1–48% PDB, 78–68% LGB, dominantly controlled by their aromaticity min...

To determine the optimal media conditions for the detection of the extracellular cellulase activity in Ganoderma neo-japonicum, we varied three media conditions: dye reagent, pH, and temperature. We evaluated the use of four dyes, Congo red, phenol red, remazol brilliant blue, and trypan blue. To observe the effect of pH on the chromogenic reaction, we tested media ranging from 4.5 to 8.0. To r...

To evaluate which dye is effective in a plate assay for detecting extracellular cellulase activity produced by fungi, four chromogenic dyes including remazol brilliant blue, phenol red, congo red, and tryphan blue, were compared using chromagenic media. For the comparison, 19 fungal species belonging to three phyla, ascomycota, basidiomycota, and zygomycota were inoculated onto yeast nitrogen-b...

An extracellular H(inf2)O(inf2)-requiring Remazol brilliant blue R (RBBR) decolorizing enzymatic activity was found in the culture medium of Pleurotus ostreatus. The enzymatic activity was maximally obtained in idiophase, and the optimum C/N ratio was 24. High C/N ratios repressed the enzymatic activity, and addition of veratryl alcohol had no effect on the production of enzyme. The enzyme was ...

Water pollution has become a major issue in many countries, including Malaysia. Malaysia is one of the countries that suffers from this detrimental influence on water resource sustainability. Adsorption been discovered to be cost-effective and efficient method removing contaminants such as pigments, dyes, metal impurities. Many biomass-based adsorbent materials have successfully used for remova...

Pleurotus florida produces two extracellular laccase (L1 and L2) isoenzymes and the L1 isoenzyme is dominantly involved in the dye decoloration process. L1 isoenzyme was successfully purified to 6.4 fold with a yield of 36% and had a specific activity of 52.6 U mg of protein. The purified laccase was monomeric with an apparent molecular mass of ≈54 kDa. The optimum pH and temperature of the LI ...

Environmental pollution may be considered one of the main problems affecting world population. As effluents from textile industries are largest representatives sources water bodies due to disposal colored compounds in environment. Microorganisms capable thriving wastewater exhibit metabolic machinery synthesize a wide variety enzymes and/or secondary metabolites industrial interest. The present...
